ANDREW J. CRAIG, OF ASHMORESTATION, ILLINOIS.

Letters Patent No. 82,923, dated October 13, 1868.

IMPROVEMENT IN minnows.

The Schedule referred to in these Letters Patent and making part of thesrdne means of rivets, bolts, screws, or in any other suitablemanner,and forming two sides of a triangle, cross-bars being placed atconvenient distance from each other,

and attached to the. teeth in the same manner that the teeth arefastened together, on which cross-bars the handles are fastened.

In order to enable others skilled in the art to make and use myinvention, I will now proceed to describe its construction andoperation, referring to the annexed drawings which form a part of thisspecification, and

in which- Figure 1 is a side view, and Figure 2, a plan view;

A. A represent the teeth, which may be made of any.

'Ihese teeth are fastened together by rivets B B, in

such a manner that the rivet passes through the front end of one tooth,and through the point of the next,

where the same is bent forward, thus forming a complete chain of teeth,of such length as may be required.

Two of these chains are made, which are fastened together at the frontby a rivet through one middle tooth, as shown in fig. 2. This middletooth is bent forward and then upward, forming a hook, G, to which theteam is attached in the most convenient manner. The chains of teeth thusfastened together spread outward toward the rear, forming two sides of atriangle, and over the last tooth-0n each chain isa crossbar, D,attached.

This cross-bar is fastened at each end to an angular bar, E, which isbent downward, and riveted to the rear tooth at the same point and inthe same manner as the teeth themselves are fastened to each other.

'lhe crossbar I) is provided with two standards, F E, which areconnected at top bya rod, a, and support on their outer side the handlesG G, these being pivoted thereon by rivets 0r bolts, 0 Z), and extendingforward to another cross-bar, H, which is placed at a suitable distancefrom the first cross-bar, and fastened to the teeth in like manner.

The handles are attached to the cross-bar by means of metalhooks, cc,runningthrough holes .in the metal staples, cl 4, on the bar.

Having thus fully described my invention,

\V'hat I claim as new, and desire to secure by Letters Patent, is

The bent teeth A A, pivoted together as described, so as to form abarrow with flexible sides, substantially as and for the purposes hereinset forth.

In testimony that I claim the foregoing, I have hereunto set my handthis 14th day of May, 1868.
